What did you do to UNDO!!!
I just update the photoshop to 2019 and found this annoying change, the undo or CTRL+Z button.
Normally I press CTRL+Z to undo and press it again to redo. Just to check the change back and forth. Now it just continuously go back which is so annoying. We can do that with CTRL+ALT+Z. Why you have to make things confusing? Especially when I do the liquify, it confuses me a lot.
Please just change it back. I believe many people want this.
